DNA polymerase (pol) β is a member of the X-family of DNA polymerases and plays an important role in base excision repair that cleanses the genome of simple base lesions.[1] It has been the subject of extensive studies examining its key roles in repair [2] and cancer.[3]In an effort to identify features of the pol β active site that modulate nucleotide binding, we have made modifications in the triphosphate moiety and studied the effect on enzyme binding, specificity, and chemistry.[4] Replacement of the Pα-OP β bridging oxygen with a carbon atom prevents catalysis,[4b] whereas modification of the Pβ-OP γ bridging oxygen alters leaving group properties.[4a] The introduction of these substituents may also enable entirely new bonding (or repulsive) active site interactions, not present with the natural nucleoside triphosphate, and thus could inform mechanistic insight as well as inhibitor design seeking to exploit pol β as a drug target.[4a]
